WESTFIELD – State police continue to keep their eye out for a small dog, one of at least three, that were spotted in the westbound lanes of the Massachusetts Turnpike Sunday morning.

“We haven’t gotten any calls today, but, if I do, I will send people down,” said Sgt. Edwin E. Lockhart, who is attached to the Westfield barracks.

One of the dogs, an English setter, was struck by a vehicle and killed, said Kenneth E. Frazer, who runs the city’s animal shelter at 178 Apremont Way.

A second dog, a Corgi-mix, was safely captured and brought to the shelter, Frazer said. It will be held at the shelter for 10 days, if nobody claims the dog it will then be available for adoption, he said.

Although initial reports indicated that two unharmed dogs were captured and taken to the shelter, Frazer said he received just the one.

The dogs were initially spotted about 6 a.m., not far from the West Springfield line. Lockhart said he did not know how they got onto the turnpike.

Lockhart said he received numerous calls about the dogs from motorists on the turnpike. “They just appeared and then disappeared and then they reappeared again,” Lockhart said of the numerous sightings.

Other motorists stopped at the barracks to report the stray dogs and some even stopped on the turnpike in an attempt to help capture them. “Which I wish they wouldn’t do,” said Lockhart, adding that it can be dangerous to stop and get out of a vehicle on the turnpike.
